Grade Details - Key Grade Characteristics
The SGM00328 utilizes Kyocera's proprietary ultra-fine grain carbide substrate (grain size 0.3 μm) with an advanced nano-composite PVD coating system. This substrate-coating combination delivers:
- Substrate Hardness: 93.0 HRA - exceptional wear resistance for micro-scale cutting edges
- Transverse Rupture Strength: 4,500 MPa - critical for preventing catastrophic fracture in small-diameter tools
- Coating Technology: TiAlSiN multi-layer architecture providing oxidation resistance up to 1,000°C
- Coating Thickness: 1.5 ± 0.2 μm - minimizes edge rounding while maintaining coating integrity
- Coefficient of Friction: 0.32 (dry) - reduces built-up edge and improves surface finish quality
- Edge Radius: 2-4 μm controlled edge preparation - balances sharpness with edge stability

Chipbreaker Profile
The SGM00328 features a specialized flute geometry engineered for micro-scale chip formation and evacuation. The design incorporates:
- Variable Helix Design: Minimizes harmonic vibration and regenerative chatter during ultra-high-speed rotation
- Positive Radial Rake Angle: 8° rake reduces cutting forces and minimizes deflection in slender tools
- Wide Flute Gullet: Optimized cross-section for chip evacuation given the extreme length-to-diameter ratio
- Polished Flute Surface: Ra 0.10 μm surface finish minimizes chip adhesion and built-up edge formation
- Edge Preparation: Controlled micro-honing of 2-4 μm ensures edge stability without sacrificing sharpness
- Center Cutting Capability: Allows direct plunging and helical ramping for pocket milling operations
Recommended Applications & Workpiece Materials
This micro endmill is specifically optimized for machining tool steels, stainless steels, and aluminum alloys. The 2-flute design and 0.032" diameter make it ideal for aerospace component finishing, injection mold micro-cavities, and precision electronics.

Recommended Cutting Conditions
Note: Values are starting recommendations for high-speed spindles (≥40,000 RPM). Optimize based on machine rigidity, spindle capability, and workpiece fixturing.
| Workpiece Material | Cutting Speed Vc | Spindle Speed n | Feed per Tooth fz | Table Feed Vf |
|---|---|---|---|---|
| Carbon Steel (P.1) | 50 m/min | 19,576 min⁻¹ | 0.005 mm/z | 195 mm/min |
| Alloy Steel (P.3) | 40 m/min | 15,661 min⁻¹ | 0.005 mm/z | 156 mm/min |
| Stainless Steel (M.1) | 40 m/min | 15,661 min⁻¹ | 0.003 mm/z | 93 mm/min |
| Aluminum Alloy (N.1) | 120 m/min | 46,983 min⁻¹ | 0.008 mm/z | 751 mm/min |
| Copper / Brass (N.1) | 150 m/min | 58,728 min⁻¹ | 0.008 mm/z | 939 mm/min |
Operating Guidelines
- Spindle Speed: Minimum 40,000 RPM recommended. For optimal performance, use air-turbine or high-frequency spindles capable of 19,576+ RPM.
- Coolant Strategy: Mist coolant or minimum quantity lubrication (MQL) preferred. Avoid flood coolant that can induce thermal shock and deflection in micro tools.
- Runout Control: Maintain total indicated runout (TIR) below 0.0002" (5 μm) at the tool tip. Even minimal runout drastically reduces tool life in micro endmills.
- Depth of Cut: For roughing, limit axial depth to 0.406 mm (0.5×D). For finishing, reduce to 0.163 mm maximum.
- Entry Strategy: Use helical ramp entry with maximum 2° ramp angle. Avoid direct plunging except for center-cutting applications.
- Tool Overhang: Minimize overhang to 38.1 mm or less. Use shortest possible tool holder and minimize stick-out to prevent vibration.
- Workpiece Fixturing: Rigid clamping is essential. Any workpiece movement at micro-scale will result in tool breakage or poor surface finish.
- Pre-Machining Inspection: Verify tool integrity under magnification (≥20×). Do not use tools with visible edge chipping or coating delamination.
Toolholder Compatibility
| Holder Type | Collet / Bore Size | Compatibility | Notes |
|---|---|---|---|
| Spring Collet (ER) | ER11 / ER16 (1/8" / 3.175 mm) | ★★★★★ Excellent | Use ultra-precision collet (AAA class) with ≤0.0002" runout |
| Hydraulic Chuck | 3.0 mm / 1/8" | ★★★★★ Excellent | Best vibration damping for high-speed micro-machining |
| Shrink Fit Holder | 3.175 mm (1/8") | ★★★★☆ Very Good | Excellent runout control; requires low-temp induction system |
| Milling Chuck (Power Chuck) | 3.0 mm / 1/8" | ★★★★☆ Very Good | Good gripping force; verify runout before use |
| Weldon Side-Lock | 1/8" (3.175 mm) | ★★☆☆☆ Fair | Not recommended for micro tools; high runout risk |
